  • Yes. A perpetual license just means no fixed end date, not that it’s irrevocable or interminable.

    You can probably get away with continuing to use ESXi free licenses even commercially, you just won’t have support. And at home, nothing is going to stop existing versions from working.

    Incidentally, assuming I found the right license agreement: https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/downloads/eula/universal_eula.pdf

    It doesn’t actually say it’s perpetual. It only says “The term of this EULA begins on Delivery of the Software and continues until this EULA is terminated in accordance with this Section 9”, but that section only covers termination for cause or insolvency, there is no provision for termination at VMware’s discretion. So, while I’m not a lawyer, it definitely sounds like you can continue using ESXi free.

    Actually, reading further, I think the applicable license is this one: https://www.vmware.com/vmware-general-terms.html

    But that one has even less language about license term and termination. Although it does define “perpetual license” as “a license to the Software with a perpetual term”, again not irrevocable or interminable.













  • A singularity is the single point mass at the center of an ideal (Schwarzschild) black hole. But mathematically, that can only happen if the mass that forms the black hole isn’t rotating. In reality, all the mass in the universe is moving around, because mass is not distributed uniformly, so gravity is pulling stuff around in a big mess. So when a black hole forms, it’s definitely a rotating (Kerr) black hole.

    A rotating mass has different gravity than a non-rotating mass. Not by much, but when you’ve got the enormous mass of a black hole, it becomes significant. This causes objects “falling into” a black hole to “miss” the point at the center, and form more of a cloud during spaghettification.

    The article is fairly accessible if you sit down and read it.

    Honestly, inside the event horizon, everything stops making sense compared to our day-to-day experiences. The immense gravitational forces distort space and time. It doesn’t really make sense to think about objects remaining intact as recognizable objects once they cross the event horizon.
